PROCEDURE FOR RECORDING CARTON FORMAL DATA STORAGE

摘要

The invention relates to a method and apparatus for producing card-shaped data carriers. The method has at least one production step requiring a data carrier of a defined type or quality or in a defined position and/or changing the data carrier in irreversible fashion or in a fashion which can be reversed only by additional expense. The data carrier is optically tested before or after said production step, and the further processing of the data carrier controlled depending on the result of said test.
